The geomagnetic severe storm on November 7-11, 2004 had Dst=-383 nT and had probably caused by the coronal mass ejection (CME) in interplanetary space. The burst of solar X-ray preceded the halo-ejection of solar plasma. The experimental fact testifying the global response of the geomagnetic field ("crochet" type) observed after the solar flare on November 6, 2004 is given. The reaction in the geomagnetic field lasted for several hours as well as X-ray bursts registered aboard GEOS-12.

DMSP satellite observations and magnetic measurements at the Yakutsk observatory (φ=62°N, λ=129.6°E, L=3.3) are used to investigate the characteristics of undulations of the equatorward boundary of diffuse aurora and their relationship to the Pc5 magnetic pulsations in the evening sector during two successive magnetic superstorms at the beginning of November 2004. The large-scale undulations were observed by DMSP satellites near Yakutsk (φ~59-62°) at 0924-0932 UT on November 8, 2004 during the storm recovery phase and at~0841 UT on November 10, 2004 during the main phase of storm. They had the wavelength of λ450-500 km and the the amplitude of A~150 km for the first event, and λ~250 km and A~100 km for the second event, respectively. The estimated velocity of westward propagation for undulations during the first event was equal to V~1.4 km/s. The appearance of undulations for both events near Yakutsk was accompanied by geomagnetic Pc5 pulsations with periods of ~4-8 min, registered at the station. The behavior of undulations and fast plasma flows with concurrent Pc5 pulsations is discussed.

Large-amplitude morning Pc5 magnetic pulsations during the main phase of intense magnetic storm were registered at magnetic stations of 190-200° magnetic meridians on January 21-22, 2005. Magnetic pulsations in the Pc5 frequency range observed at the GOES 10, 12 satellites in the noon and evening sectors exhibited a high degree of magnetic compessibility. A Los Alamos particle detector on board geostationary satellite observed the occurrence of energetic particle flux oscillations in the Pc5 band. The Pc5 pulsations were followed with the VLF-emission and riometer absorption modulation with the same period. The regions of maximal amplitude of Pc5 geomagnetic pulsations and deep modulation of riometer absorptions shifted to high latitudes in the same way. Significant and long-lasting compression of magnetosphere led, probably, to moderate pitch-angle diffusion of particle into the loss cone even at the middle latitudes. Analysis of coordinated data allowed us to suggest that a modulation effects of precipitating particles are caused by a compressional waves.

The 20.11.03 super-storm is described on the basis of the quantitative estimations of input and output parameters of the magnetospheric disturbance energetics. Two input parameters are ε'- Poynting flux from solar wind into the magnetosphere, and the polar cap potential drop Upc. The output parameters (indicators the magnetospheric responses) are the total power of the magnetospheric disturbance (Qt), and the powers consumed in the ionosphere (Qi) and in the ring current (Qdr). Different modes of the magnetosphere disturbances are shortly described: substorms, driven mode, Null Events by Lyons et. al., saturation of the ionosphere, and responses to a strong s. w. pressure pulses. The problem of the substorms-storm relationship is also addressed.
